To all whom it may concern:

Be it known thatll, EDWARD H. ELLIsON, a citizen of the United States,residing at Jamestown, in the county of Chautauqua andState of New York,have invented certain new and useful Improvements in Radiators orCoolers, of which the following is a specification. I

The invention relates to new and useful improvements in radiators forautomobiles and more particularly to the construction of theconduitsthereof.

An object of the invention is to provide a radiator wherein the sideplates forming the conduits are all similarly bent and shaped and are soconstructed as to have an extended surface contact at the point ofattachment between the adjacent conduits.

A. further object of the invention is to provide a radiator of the abovecharacter wherein the side edges of the plates forming the conduits arebrought into contact throughout their entire length, thus reducing to aminimum the amount of solder necessary for connecting the same.

A still further object of the invention is to provide a radiator of theabove character wherein the side edges of the plates forming eachconduit are in contact throughout with alternately'large and smallbends, the angles of which are of the same magnitude and face in thesame direction .so that the outer face of the larger bend in one conduitmay nest in the smaller bend of an adjacent conduit and be securedthereto throughout the entire length of the smaller bend.

These and other objects will in part be obvious and will in part behereinafter more fully disclosed.

In the drawings, Figure 1 is a front elevation of the radiator partly insection and partly broken away, the sectional p'artbeing taken on theline 1"1 of Fig. 2. Fig. 2 is a sectional elevation taken transverselythrough the radiator, the end water course of the section being shown-infull lines andthe water tanks at the top and bottom being shown insection. Fig. 3 is a detail perspective view of three consecutive platesthat are used to form the water courses, the one at'the leftand themiddle one being joined together atflthe edges to form a complete watercourse and the one at the right formlng one side of the next watercourse. Fig. 4 is a section taken through, four plates on the lineindicated by 4*4* of Fig. 3, show- ;ing two completed water coursesspaced apart, the intermediate part of the water course, where thesection is taken, being shown in full lines, while the edge of the watercourse, where the sidesare shown together, being shown in dotted lines.Fig. 5 is a sectional elevation of the water courses, showing amodification of what is shown in Fig. 4, a single division or partitionplate being used between two consecutive Water .courses. F1g. 6 is anenlarged view of the joints between the consecutive water courses andthe water tank at the top on the section line 6"6" of Fig. 2. Fig. 7 isa modified form of thewater courses.

My improved radiator 1 consists of a'water chamber 2 located at the topof the radiator and a water chamber 3 located at the bottom thereof.Between these chambers there are a plurality of conduits 4 and myinvention is directed to the constructionof these conduits. Each of theconduits is made up of two plates 5 and 6 which are formed from a sheetof thin metal, preferably of brass or copper. The edges of these platesare drawn and shaped to ofiset. them from the intermediate part so thatthe plates between the side edges will be spaced to form a passage 10,through which the water passes from the chamber at one end of theconduit to the chamber at the other end thereof. These side plates arepreferably bent so as to form substantially vertical portions 5 andinclined portions 6 located between the vertical portions. Theseinclined portions extend at an acute angle to the vertical line so thatthe passage 10 formed by the side plates is not only a continuouspassage but it is free from all horiother a relatively small amount ofsolder is necessary for joining the same. These side edges are alsoshaped so as to form large bends 10 and small bends 10". Theserelatively large and small bends are arranged alternately and the metal,of course, forming the bends is connected, one bend leading into thenext. The angles of the bends are of the same magnitude and face in thesame direction, as will be clear from an inspection of the drawings.

While I have referred to the plates 5 and 6 as similarly shaped it willbe understood that this term is used in the sense that certain sectionsof the plates are exact duplicates of 'each other, that is the sideedges,

while the intermediate sections have the same general shape. The sideedges must be offset relative to the'intermediate parts so that when aset of plates is brought to-\ gether to make a conduit they will beoffset to form a passage therebetween for the water course. This isaccomplished by having the offset in one plate opposite to that of theother plate. After the side plates, forming the conduits are broughttogether, then another conduit is formed and the large bends arenested'in the smaller bends of the adjacent conduit. That is to say, theouter face of the large bend at the vertex of the angle is nested in thesmall bend and this outer face makes contact with the inner wall of thesmaller bend throughout the entire extent of the smaller bend. A

Figs. 1 and 2 of the drawings clearly show the larger bends nested inthe smaller bends as described above.

vVhen solder is applied to the edges, the relatively large surfacebetween adjacent conduits will be joined by the solder, the solderextending along the contacting edges of the entire small bend. Thismakes a very strong connection between the adjacent conduits and greatlyincreases the strength of the radiator.

From Figs. 4 and 6 of the drawings it will be apparent that the vertexof the angle of the large bend projects beyond the vertical wall 5 inthe plate forming the conduit and this projecting of the larger bendbeyond this vertical wall is particularly for the purpose of spacing.vertical walls '5 of adjacent conduits, thus forming not only horizontalair passages 11 bqt also vertical angular portions 6* ofthe conduit,while in Fig. 6 I have shown these edges ascoinciding with the medialline between these portions. This is immaterial as theedges may bearranged in either of the ways shown. 4

In Fig. 5 of the drawings I have shown a slightly modified form-ofconstruction of radiator. The water conduits are indicated at 15 and 16and these are formed vfrom plates shaped as described above. Betweenadjacent water conduitsthere is a separating plate indicated at 17,which is in the form of either of the side plates forming the conduit asthe side edges of these plates are the same.

In rolling the brass or copper to the very thin gage required, pin holesand other similar imperfections frequently occur. If. these exist tosuch an extent that they cannot be From the above it will be apparentthat I have provided'a radiator for automobiles or the like wherein theconduits are formed from lates which are similarly shaped throughout thelength of the conduit. Furthermore, these plates are so formed that theside edges which are joined to form the conduits'are in contactthroughout the entire length, thus reducing. to a minimum the amount ofsolder necessary for joining said edges Furthermore,'these side edgesare so shaped as to form large and small bends, which small bendsreceive a portion of the larger bends of adjacent conduits, thus greatlyfacilitating the assembling of the parts and holding the adjacentconduits in the proper position for soldering until they have beendipped. Furthermore, this nesting of the larger bendin the smaller bendgreatly strengthens the radiator as it provides a large contactingsurface between the adjacent conduits.

The manner of connectingthe side plates of the conduits at the upper andlower edges thereof to each other and to the water chamber is of thewell known construction and description thereof is not thoughtnecessary.

It is obvious that minor changes in the details of constructionmay bemade without departing from the spirit of the invention as set forth inthe appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Let-. ters Patent, is

1. A radiatorfor automobiles including I in combination a plurality ofconduits, each conduit being composed of similarly shaped platesbent soas to form therebetween a continuous passage, the side edges of saidplates being bent so as to have contact throughout the entire length ofthe conduit and so as 1 ,eoaeva to space the plates to form saidpassage, said side edges having formed therein alternately relativelylarge and small bends the angles of which are the same and face in thesame direction whereby the outer face of the larger bend in one platemay nest in and be firmly secured in the smaller bend of an adjacentplate.

2. A radiator for automobiles including in combination a plurality ofconduits, each being composed of similarly shaped plates bent so as toform therebetween a continuous passage having vertical portions andinclined portions connecting said vertical portions, the side edges ofsaid plates being bent so as to have contact throughout the entirelength of the conduit and so as to space the plates to form saidpassage, said side edges having formed therein alternately relativelylarge and small bends, the angles of which are the same and face in thesame direction, said larger bend projecting beyond the vertical Wall ofthe conduit to such an extent that when nested in the smaller bend ofthe adjacent conduit the Walls of said adjacent conduit will be spacedto form vertical air passages.

3. A radiator for automobiles including a plurality of conduits, eachbeing composed of similarly shaped plates bent so as to formtherebetween a continuous passage, the side edges of said plates beingbent so as to have contact throughout the entirelength of the conduitand so as to space the plates to form said passage, said side edgeshaving therein alternately relatively large and small bends the anglesof which are the same and face in the same direction, saidconduits beingarranged side by side with the large bends in the side edges of theplates forming one conduit nested in the small bend in the side edges ofthe plates forming the adjacent conduit and secured thereto throughoutthe entire length ofsaid small bend.

In testimony whereof I affix my signature.
